I got something: Was a samurai, involved in the rage of the war, mercyless and wrathful, killed he's way trough to the top and become general, he always joined the battle, and the bodies that he have left without life, were enough to make the biggest mountain. His family, Wife and two kids, was threated with death, but he maked the first step, killing them all, His mentality was disturbed, twisted and hopeless. He got ambushed in his bedroom and killed by enemy. A misteryous woman showed at hes funeral, leaved a silver necklace with a black gem in his neck, the guards, saw this unrespectul act and attack her. But, somehow the guards got killed and the woman retired without a trace. Three days passed and the body of the samurai wasn't there, there was only a note, with tint letters: " I'll get vengeance ". Now the body of the samurai walks, following the misteryous lady, everywhere, killing what he's told, with an armor and two swords that are her gift, taking no damage of the wounds by the shimmering metal of the enemies swords. "The puppet dances with the song of fight, leaving his enemies cercenated, and with no chance to opposite their fate of becoming one of his mountain of dead bodies. With no regret of his past".
